To will whom t may concern.-

lBe it known that I, HENEIETTA McGEEGoR HULL, a citizen of the UnitedStates, residing construction illustrated in the accompanying fdrawings, in which- Figure 1 is a side view of the carriage ready Fig. 2is a' front end View of the carriage-frame. Fig. 3 is aside View of theframe when collapsed. Fig. 4 is an end view of the same. Figs. 5 and 6show a detail'of the hammock-support. Fig. 7 is a button to turn theshaft that controls the position of the wheels. Fig. 8 is a detail ofthe toggle-links that control the position of the wheels. Fig. 9 is anelevation of the lock of the front hammocksupport and the handle. Fig.10 is a view of the same, taken along the line of the arrow in Fig. 3.Fig. 11 is an enlarged view of the pin that controls this lock, and Fig.12 is a View of the end of one of' the links of the same.

Similar reference characters refer to like parts throughout the severalviews.

The frame of the carriage is composed of the front and rearcross-bars 1,which carry bearings 2 for the side bars 3. -The middle brackets 4 andend brackets 5 support the wheels 6, it being understood that there aretwo middle brackets 4 between each pair of wheels, one on each side ofthe wheels. To each end of each side bar is attached a crank 7. To thecenter of each cross-bar is attached the bearing 8, which bearingscarrythe shaft 9, which shaft has attached to it outside of each bearing adouble crank 10, whichis connected by the links l1 to the cranks 7 onthe side bars. Thisrshaftzmay be turned by the button 31, securedtoeither the front or rear end of the shaft outside of the double crank onthat end. In'Fig. 8 it will be noticed that the outer end of the link 1lis slotted. The throw of the side of the crank 10, to which Serial No.16 8,383. (No model.)

this link is attached, is slightly longer than `that of the other sideto allow for this slot, fthe object being to delay the swinging of thewheels on one side, so that there will be no interference between thewheels. The toggle at the other end of the carriage is similar.

A pin on the crank and another on the bearing prevent the wheels on theside with the slotted link from swinging out farther than at rightangles. (See Fig. 8.) The double cranks are permitted a little more thanonehalf of a revolution, so that the pins will pass beyond the centereach time and act as a par- Itial lock.

To the bearings 2 are attached brackets l2, having notches 13 and pins14. The front hammock-support ,15 and the handle 16 have metal stirrups17 at their lower ends slidable on the pins 14, which stirrups areprovided with pins adapted to enter the notches 13. Links 1S are securedat one end to these stir- ,rnps and are joined in the' center bymeansdle, as shown in Fig. 1, permitting the same to be folded againstthe carriage-handle. The

hammock shown is provided `with spreaders 23 and 24. The front end ofthe hammock is secured to the necks of pins 25, while the rear isprovided with springs 26, which connect with the pivoted arms 27,supported by the cross-piece 2S. This cross-piece has a pin 29 at eachend, which may enter any of the notches 30 in the arm 27, so that thesearms may be held at the angle desired.

To collapse the carriage, the front hammock-support is rst released tofall back by pulling the pins out of the notches 13 byturning the pin19. The handle is then dropped forward in the same manner. lNext'jthebutton 3l is turned and the wheels fold up, when the now collapsed,structure may be carried by one of the side bars.

l have shown the cross-piece 28 and the end ICO and side bars of tubing;but wood may be used instead. It is obvious that many changes may bemade in this structure-without departing from the scope of my invention.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. In a collapsible carriage,the combination of the wheels, axles forsaid wheels, a frame, rotatable side bars, and brackets whereby thewheels are carried by the side bars.

2. In a collapsible carriage,the combination of the cross-bars, sidebars, wheels supported by the side bars, and toggle-links to turn theside bars.y

3. In a collapsible carriage,the combination of rotatable side bars,depending braces, Wheels carriedwby said braces with their axles belowthe line of said side bars, and means to turn the side bars.

4. In a collapsible carriage,the combi nation of a frame `comprisingfront and rear crossbars, bearings carried by said cross-bars, side barsjonrnaled at their ends in said bearings and wheels carried by said sidebars.

5. In a collapsible carriage,the combination of the frame, bearingssecured to the front and rear ends of the frame, side bars extendingfrom the front to the rear bearings and rotatable in the same, wheelscarried by the side bars, a carriage-handle secured to one end of theframe, a support secured to the other end of the frame, a hammockattached at one end to said support and at the other end to said handle,and springs forming the connection between the hammock and handle.

6. In a collapsible carriage,the combinationof a frame comprising frontand rear crossbars, bearings carried by said cross bars, side barsextending from the front to the rear bearings and rotatable in the same,wheels carried by the side bars, a carriage-handle pivoted to the rearend of the frame, a support pivoted to the front end of the frame, ahammock carried by the support and handle and locking means to securethe handie and support in their elevated position.

7. Inacollapsiblecarriage,thecombination of cross-bars having bearingsat their ends, side bars revoluble in said bearings, wheels carried bysaid side bars, cranks on the ends of said side bars, a shaft supportedby said cross-bars, and toggle-links carried by said shaft and attachedto said cranks so that the turning of the shaft will swing said wheelsto collapse said carriage.

8. Inacollapsiblecarriage,the combination of the cross-bars havingbearings at their ends, brackets on said bearings, rotatable side bars,wheels carried by said side bars, a hammock, supports for said hammockpivoted on said brackets, and means to lock said supports to saidbrackets to hold the same in elevated position and to unlock thesupports so they may be folded down on the side bars.

9. In a collapsible carriage, the combination of the frame, comprisingrotatable side bars, wheels carried by the. side bars, hammocksupportspivoted to the frame, a cross-bar on one of the supports, arms pivotedon said cross-bar, means to lock said arms in the desired angularposition, springs secured to said arms and a hammock carried by thesprings and the other support.v

10. In a collapsible carriage, the combination of the cross-bars,bearings at the center of the cross-bars, a shaft carried by saidbearings permitted to turn over one-half revolution each way, doublecranks on the ends of said shaft having pins at unequal distances fromthe center, bearings at the ends of said cross-bars, side bars revolublein said bearings, Wheels carried by said side bars, cranks at the endsof said side bars, links connect-v ing the pins of the double cranks tothe cranks on the side bars, one end of the links connected to the pinsthe greater distance from the center of the double cranks being slotted,and means to limit the movement of the side bar adjacent to the slottedlinks.

l1. In a collapsible carriage, the combination of a frame, bearings atthe ends of said frame, side bars each journaled in several of saidbearings, wheels carried by said side bars, and means to turn the sidebars to swing the wheels up under said frame.

12. In a collapsible carriage, the combination of a frame, bearingscarried by said frame, side bars rotatable in said bearings and aplurality of Wheels carried by each side bar.

13. In a collapsible carriage, the combination of front and rearcross-bars, bearings at the ends of said cross-bars, side bars extendingfrom the front to the rear bearings, aplurality of wheels carried byeach side bar, and means to turn the side bars.

14. In a collapsible carriage, the combination of a frame, comprisingrotatable side IOO IOS

bars and bearings for the same, braces secured to the side bars, axlescarried by the braces, wheels mounted on the axles, and means to turnthe side bars.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
